| 内容記述 | Concerns have arisen over increases in the scale and frequency of localized torrential down-pours and other meteorological disturbances accompanying climate change, and it is predicted that such climatic conditions will lower ood control safety on rivers. There are also concerns about the opposite risk, of drought, and measures for maintaining river safety and stable water provision have been called for. More sophisticated management of multipurpose dams has been proposed as a measure for improving ood control while maintaining of water availability. In light of the above, ood control during the snowmelt season has become a problem for dams in snowy regions. During the past several years, we have experienced heavy rains during the snowmelt season, which had been considered a season with few heavy rainfall events. There have been cases in which the dam operators were unable to respond properly by using conventional fl ood control techniques. Toward addressing this, the present study aims at improving dam functionality. Pre-release of some of the dam water that is kept for use is one potential measure for improving the functionality of a multipurpose dam; however, this entails a risk in the loss of water for use. Proper pre-release requires that we determine when to release water and how much to release, based on the prediction of how much water for use can be secured after the release. These two items should be properly determined if pre-release of dam water is employed as a ood control measure against heavy rainfall during the snowmelt season. Use of runoff forecasting has been examined for determination of when to start pre-release; however, it has not been clari ed whether such forecasting is effective in securing proper storage and safety. In this study, an analysis of the forecasting accuracy of hydrological information, including that on precipitation and that on runoff, revealed that forecasts of cumulative pre-cipitation were advantageous. Based on the analysis results, we propose a technique for using accumulative forecasted precipitation in timing the pre-release, and we demonstrate the efficacy of the technique in securing safety in ood control and reliability of water availability. Concerning the risk of pre-release leading to storage insufficiencies, we constructed a computational model for estimating the water storage capacity of a dam watershed, and we proposed a new technique for determining the minimum water level for securing water for use even after pre-release. We conducted a simulation assuming that our forecast was "wrong" and proved that our proposal is effective in securing reliability of water availability when pre-release is carried out. | |||||||||||||
